DETAILED DESCRIPTION
[0032] Referring to FIG. 1, an inertia bullet remover of the
present disclosure is indicated generally by the reference number
10. As will become apparent, the remover 10 is configured to remove
a bullet from a case or shell (broadly, "ammunition casing") of a
firearm cartridge. The remover 10 removes the bullet by moving the
cartridge rapidly and then suddenly stopping the cartridge while
holding the case such that inertia causes the bullet and powder
from inside the case to exit the mouth of the case.
[0033] The remover 10 includes a base 12, a carriage 14, and a
carriage driver 16 for driving movement of the carriage with
respect to the base. Using any one or more of fastener holes 18,
the remover 10 can be mounted (e.g., in a vertical orientation) by
fasteners to any suitable structure, such as a wall or a reloading
bench. It will be appreciated that bullet removers may configured
to operate in any other orientation without departing from the
scope of this disclosure.
[0034] The base 12 includes a frame 13 and a track (broadly,
"guide") on which the carriage 14 is movable. In the illustrated
embodiment, the track comprises two rods (broadly, "rails") 20
extending from an upper rod connecting portion 22 of the frame 13
to a lower rod connecting portion 24 of the frame. The rods pass
through openings in the rod connecting portions 22, 24 and are
secured in position by nuts on opposite ends of the rods. The nuts
on opposite ends of a rod 20 are tightened to oppose the rod
connecting portions 22, 24 of the frame 13 to tension the rod and
apply compression to the frame between the rod connecting portions,
for reasons which will become apparent. The base 12 includes a stop
28 defining a stop surface for stopping movement of the carriage
14. The base 12 also defines a holder 30 (FIG. 6) for holding a
bullet and powder container 32 (e.g., trap) arranged to catch a
bullet and powder ejected from a case held by the carriage 14.
[0035] In the illustrated embodiment, the container 32 includes two
sleeves 32A configured to fit over ends of the rods 20 to locate
the container on the base. The base 12 includes a resiliently
deflectable latch 34 configured to hold the container 32 in
position. To install the container 32, the container is moved onto
the ends of the rods. The container 32 pushes the latch 34
rearward, and the latch temporarily deflects and then resumes its
at rest positon after the bottom of the container passes a tooth
34A of the latch. The tooth 34A supports the bottom of the
container 32 to hold the container in position on the rods 20. To
remove the container 32, a user presses the latch 34 rearward to
permit the container to be moved off the rods 20.
[0036] The carriage 14 is configured to hold an ammunition case or
shell from which a user would like to remove a bullet. The carriage
14 includes followers 40 defining openings through which the rods
20 extend. The followers 40 permit and guide movement of the
carriage 14 along the rods 20 for ejecting a bullet from a shell
carried by the carriage.
[0037] The carriage 14 includes a carriage housing 42 on which a
cartridge carrier 44 is mountable. The carriage housing 42 defines
a cavity in which the carrier 44 is receivable. The carriage
housing 42 includes a front opening that is closed by the carrier
44. The carrier 44 includes a carrier housing 44A defining a
cartridge compartment 46 (FIG. 9) in which cartridges of different
types and sizes are receivable. The carrier 44 includes a shell
holder mount 48 configured to receive standard shell holders 50
(broadly, "ammunition casing holder") configured to hold different
types of shells. The shell holders 50 are interchangeable on the
mount 48 for adapting the remover 10 for use with different types
of cartridges. As shown in FIG. 10, the shell holder 50 installed
on the carrier 44 grips the shell by a flange of the shell at a
primer end of the shell and holds the shell in position for
conjoint movement with the carrier. A user can move a cartridge
into the cartridge compartment 46 and slide the cartridge into the
shell holder 50 laterally with respect to a longitudinal axis of
the cartridge. In use, a cartridge is loaded in the cartridge
compartment 46, and then the carrier 44 is installed in the cavity
of the carriage housing 42. The carrier 44 acts as a door to close
the front opening of the carriage housing 42. The carrier 44
includes a retainer 54 configured to releasably retain the carrier
in position on the carriage housing 42. In the illustrated
embodiment, the retainer 54 comprises an actuator (e.g., knob) and
a pair of latches 56 movable into and out of slots 58 (broadly,
"keepers") (FIG. 7) in the sides of the carriage housing 42 (e.g.,
by rotating the knob about 45 degrees in opposite first and second
directions) to lock and unlock the carrier on the carriage
housing.
[0038] The carriage driver 16 is configured to move the carriage 14
from a starting positon (broadly, "second position") (e.g., FIGS.
1, 2, 11) to a loaded position (broadly, "first position") (e.g.,
FIGS. 12, 13, 14, 16). After the carriage 14 is moved to the loaded
position, the carriage is released to move back to the starting
positon. The movement of the carriage 14 toward the starting
positon happens rapidly, and the carriage is stopped suddenly in
the starting position, such that inertia causes the bullet and
powder to leave the shell and be captured by the container 32.
[0039] The cartridge driver 16 includes an actuator 60, a linkage
62, a carriage pusher 64, and a set of compression springs 66
(broadly, "biasing elements") received on the rods 20. In the
illustrated embodiment, the actuator 60 comprises a lever. The
lever 60 has a distal end including a knob and a proximal end
connected to a lever mount 68. The lever mount 68 is pivotally
connected to the base 12 to pivot about a pivot axis A1. The
linkage 62 includes first and second links 62A, 62B on opposite
sides of the base 12. The lever mount 68 is pivotally connected to
upper (first) portions of the links 62A, 62B to pivot with respect
to the links about a pivot axis A2. Lower (second) portions of the
links 62A, 62B are pivotally connected to the carriage pusher 64 to
pivot about a pivot axis A3. In the illustrated embodiment, the
carriage pusher 64 includes two collars slidable on the rods 20 to
guide movement of the carriage pusher along the rods. The
arrangement is such that as the lever 60 is pivoted away from the
base 12 (e.g., from a home position to an actuated position), the
lever and lever mount 68 pivot about the pivot axis A1, which
causes the linkage 62 to pull the carriage pusher 64 upward, to
move the carriage 14 toward a loaded position of the carriage.
Before the carriage pusher 64 contacts the carriage 14, the
carriage pusher moves across a small clearance space 70 (e.g., 2
mm) (FIGS. 2, 5), for reasons which will become apparent. As the
carriage 14 moves upward, the followers 40 of the carriage press
against the springs 66 on the rods 20 and compress the springs.
[0040] The remover 10 also includes a carriage retainer 74 for
retaining the carriage 14 in a loaded position prior to releasing
the carriage to eject the bullet from the shell. In the illustrated
embodiment, the carriage retainer 74 comprises a ratchet mechanism
configured to retain the carriage in progressive loaded positions
at different compression states of the springs. The ratchet
mechanism comprises a lever 76 pivotable about a pivot axis A4
(FIGS. 11 and 16) and biased by a spring 78. The lever 76 has a
catch 80 arranged to engage a set of teeth (broadly, "keepers")
82A-82C (three teeth in the illustrated embodiment) on a rear side
of the carriage 14. The catch 80 rides on the rear of the carriage
14 and over the teeth 82A-82C as the carriage is moved upward. Each
tooth 82A-82C includes a ramped surface configured to deflect the
catch away from the carriage to permit the tooth to pass the catch.
After a tooth 82A-82C passes the catch 80, the catch is moved by
the spring 78 into retaining position with respect to a retaining
surface of the tooth. If the user were to release the lever 60, the
catch 80 would prevent the carriage 14 from moving back to its
starting position by engaging the retaining surface of the tooth
82A-82C above the catch. It will be appreciated that different
types of carriage retainers (e.g., different types of ratchet
mechanisms) can be used without departing form the scope of the
present disclosure. For example, a single tooth instead of multiple
teeth could be used such that there is a single retained loaded
position rather than progressive retained loaded positions.
[0041] The user can select the amount of compression applied to the
springs 66 by the amount the lever 60 is pivoted away from its home
position, and thus select the force at which the carriage 14 will
be moved back to the starting position. FIGS. 12-16 show the lever
60 pivoted to drive the carriage 14 to an intermediate loaded
position in which the second tooth 82B is above the catch 80. If
the user desired to drive the carriage 14 to a fully loaded
position (maximum spring compression), the lever would be pivoted
farther upward than shown in FIGS. 12-16 to drive the lowest
(third) tooth 82C above the catch 80. In other embodiments, the
force at which the carriage 14 will be moved back to the starting
position could be adjusted or selected in other ways (e.g.,
changing or adjusting a spring retainer). In still other
embodiments (e.g., not having progressive retained loaded
positions), the force at which the carriage 14 will be moved back
to the starting position may not be adjustable.
[0042] When the user desires to release the carriage 14 to cause
the bullet and powder to eject from the shell, the user pivots the
lever 60 back to its home position. As the lever 60 approaches the
home position, the linkage 62 moves the carriage pusher 64 back
across the clearance space 70 to be out of the carriage travel
path. After the cartridge pusher 64 is moved out of the carriage
travel path, releases 86 in the form of protrusions on both links
62A, 62B of the linkage 62 press on wings 76A of the spring-biased
lever 76 to move the catch 80 rearward to disengage the catch from
the carriage 14. The teeth 82A-82C are therefore no longer blocked
by the catch 80, and the springs 66 are permitted to forcefully
propel the carriage 14 toward its starting position. The carriage
14 moves rapidly toward the starting position and impacts the stop
28 of the base 12 to stop the carriage in the starting position.
The rods 20, in tension and applying compression to the base 12,
assist in reinforcing the base and absorb force from the impact of
the carriage 14 against the stop 28. The inertia of the bullet and
powder causes the bullet and powder to be ejected from the shell,
which is held in position on the carriage 14 by the shell holder
50. The bullet and powder move through a lower opening in the
carriage, through an opening in the base, and pass into the
container 32 for collecting the bullet and powder in the container.
The cartridge carrier 44 closing the front opening of the carriage
housing 42 prevents powder from escaping the carriage 14 except
through the lower opening to the container 32. The bullet and
powder can be removed from the container 32 by removing the
container from the base 12 and dumping the container. The carrier
44 is removed from the carriage housing 42, the empty shell is
removed from the carrier 44, and another cartridge is installed in
the carrier. The process can be repeated to remove bullets and
powder from additional cartridges.
[0043] It will be appreciated that the container 32 can be replaced
by any other receptacle or series of receptacles, such as a tube or
bucket, and the replacement receptacle(s) may or may not be
physically attached to the remover 10, without departing from the
scope of this disclosure. For example, as shown in FIG. 20, a
fitting 90 is provided for connection of a tube to receive powder
and bullets removed from ammunition casings by the remover 10. The
fitting comprises a tubular portion sized and shaped to fit inside
an end of a tube. The fitting 90 can include barbs, ribs, or other
retainers 92 to engage the tube to assist in holding the tube on
the fitting. It will be appreciated that a tube connected to the
fitting 90 can have an outlet end located to deliver powder and
bullets into a bucket or other receptacle.
[0044] It will be appreciated that the remover 10 provides spring
propulsion of the carriage and a mechanical advantage in
compressing the springs 66. Accordingly, users can easily generate
an amount of force needed to eject a bullet from a shell. Moreover,
standard shell holders can be used for holding the cartridges. The
remover 10 is universal in that the remover can remove a bullet
from essentially any type of ammunition cartridge with the use of
an appropriate shell holder.
[0045] A second embodiment of a cartridge carrier 144 will be
described with reference to FIGS. 21-24. The cartridge carrier 144
of this embodiment is very similar to the cartridge carrier 44
described above, and like reference numbers, plus 100, are used to
designate like elements. For example, the cartridge carrier 144 is
configured to be selectively installed on and carried by the
cartridge carriage 14. The cartridge carrier 144 includes a housing
144A and a retainer 154 including a rotatable knob to move latches
156 to releasably retain the carrier on the carriage 14.
[0046] The primary difference between the first and second
embodiments of the carriers 44, 144 is the manner in which the
ammunition cartridge is supported by the cartridge carrier. In the
second embodiment, instead of using standard shell holders (e.g.,
50 in FIGS. 10, 19), the cartridge carrier 144 includes a collet
150 configured to receive and retain ammunition casings of various
sizes. The collet 150 automatically adjusts to hold the casings of
various sizes. The collet 150 rests on a bed 145 defined by an
upper end of the housing 144A of the cartridge carrier 144. A
removable cover 144B holds the collet 150 in position on the bed
145. The collet 150 includes multiple jaws 151 movable with respect
to each other to adjust the size of an ammunition casing receiving
space therebetween. Each jaw 151 includes an arcuate lip 151A
bounding the ammunition casing receiving space and located to be
received in a groove of an ammunition casing and/or against a
flange of the ammunition casing to locate the ammunition casing
with respect to the cartridge carrier 144. An elastic band 153
(broadly, "biasing member") surrounds the jaws 151 and biases the
jaws inwardly. The elastic band 153 permits outward movement
against the bias of the band. The jaws 151 include grooves 151C
that ride on ribs 147 of the housing 144A to guide inward/outward
movement of the jaws and maintain the collet 150 in a centered
location.
[0047] The arrangement is such that an ammunition cartridge can be
installed on the cartridge carrier 144 by pushing the bullet end of
the cartridge downward into the top of the cartridge receiving
space. The tapered shape of the bullet causes the jaws 151 to move
away from each other. The jaws 151 deflect outward and ride on the
ammunition casing until the groove of the ammunition casing is
moved into registration with the lips 151A of the jaws. The jaws
151 move into the groove and thus retain the ammunition casing in
position with respect to the cartridge carrier 144. After the
bullet is removed from the ammunition casing, the casing can be
removed from the collet 150 by pushing the casing upward opposite
the insertion direction. The jaws 151 include tapered lower
surfaces 151B that cam on the ammunition casing to assist in
spreading the jaws to permit removal of the casing. It will be
appreciated that other types of collets (broadly, "ammunition
casing holders") can be used without departing from the scope of
the present disclosure.
[0048] It will be apparent that modifications and variations are
possible without departing from the scope of the invention defined
in the appended claims.
[0049] As various changes could be made in the above constructions
and methods without departing from the scope of the invention, it
is intended that all matter contained in the above description and
shown in the accompanying drawings shall be interpreted as
illustrative and not in a limiting sense.
